Anotation

IEC 62271-109:2019 is applicable to AC series capacitor by-pass switches designed for outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 52 kV. It is only applicable to by-pass switches for use in three-phase systems. This document is also applicable to the operating devices of by-pass switches and to their auxiliary equipment. This third edition cancels and replaces the second edition published in 2008 and Amendment 1:2013. This edition constitutes a technical revision. This edition contains the following significant technical changes with respect to the previous edition: a) the document has been restructured according to edition 2.0 of IEC 62271-1; b) the rated voltage assignation across the by-pass switch has been aligned to the rule defined in IEC 60143-1; c) clarification has been given regarding rated continuous current of compensated and uncompensated line; d) some clarifications have been given following a loss of "suitable precautions"; e) as per Amendment 2 of IEC 62271-100, the section "Rated time quantities" has been moved to Clause 6 under "Time quantities"; f) as per Amendment 2 of IEC 62271-100, the section "Test for static mechanical loads" have been moved to Clause 6 under "Static mechanical loads"; g) additional rules have been introduced for vacuum interrupters during impulse tests; h) additional clarifications have been given regarding the number of reduced impulses during impulse tests; i) a wider tolerance on the current damping during by-pass making current test-duty has been introduced. L’IEC 62271-109:2019 est applicable aux interrupteurs de contournement pour condensateurs serie a courant alternatif concus pour linstallation a lexterieur et pour fonctionner a des frequences de 50 Hz et 60 Hz, sur des reseaux de tensions superieures a 52 kV. Elle s’applique uniquement aux interrupteurs de contournement destines a etre utilises dans les systemes triphases. Le present document est egalement applicable aux dispositifs de commande des interrupteurs de contournement et a leurs equipements auxiliaires. Cette troisieme edition annule et remplace la deuxieme edition parue en 2008 et son Amendement 1:2013. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) le document a ete remanie selon l’edition 2.0 de l’IEC 62271-1; b) lassignation de tensions assignees aux bornes de l’interrupteur de contournement a ete alignee sur la regle definie dans l’IEC 60143-1; c) des precisions ont ete apportees au sujet du courant permanent assigne de la ligne compensee et de la ligne non compensee; d) des clarifications ont ete apportees suivant une perte des "precautions appropriees"; e) conformement a l’Amendement 2 de l’IEC 62271-100, la section "Durees assignees" a ete deplacee a l’Article 6 sous "Durees"; f) conformement a l’Amendement 2 de l’IEC 62271-100, la section "Essai des charges mecaniques statiques" a ete deplacee a l’Article 6 sous "Charges mecaniques statiques"; g) des regles supplementaires ont ete introduites pour les ampoules a vide pendant les essais de chocs; h) des clarifications supplementaires ont ete apportees au sujet du nombre de chocs reduits pendant les essais de chocs; i) une tolerance plus grande pour lamortissement du courant pendant la sequence d’essai d’etablissement du courant de contournement a ete introduite.
